Title: Improvements in means for connecting and disconnecting screwed joints
IPC: E21B19/16
Filed: 1935-03-06
Abstract: 450,778. Borehole apparatus. MULLER, F., 170, Lainzerstrasse, Vienna. March 6, 1935, No. 7084. Convention date, March 6, 1934. [Class 85] [See also Groups XXII and XXIII] In connecting and disconnecting screw joints in deep-boring appliances, two torques acting in the same direction are applied, one torque being approximately constant and the other being applied by the blows of a hammer actuated by steam, air or gas. In Fig. 2, a spanner 15 is connected to a pneumatic hammer 16 to which a pull is applied by handles 17 or a rope connected to an eye 18 ; simultaneously through lever 19 and link 20 the hammer may be started. The hammer may be arranged adjustably or fixed at any desired point on the handle of the spanner. In Figs. 4 and 5, a chain wrench with hammers 66-69 has a slotted and recessed handle 70 engaged by the rod 72 of a piston 74 working in a cylinder 73 connected by universal joint 75 to the draw-works and provided with a counterweight 76 to swing the cylinder to vertical position when inoperative. A valve 77 controls supply to the hammers 66-69 and also to the cylinder 73 to turn the wrench ; at a given pressure, the piston 74 yields against adjustable spring 79 to open ports 80 and admit fluid through the rod 72 to reciprocate a hammer cylinder 85 against a second piston 84 on the rod. A spring 86 returns the hammer cylinder to initial position. The Specification as open to inspection under Sect. 91 states also that spring or electromagnetic hammers may be used. Further, a spanner may have in its' head a pneumatic hammer 1, Fig. 1 (Cancelled), pressed by a spring against the work 3 ; hand or power means for turning the spanner may also act through lever 6 and link 5 to start the hammer. In a chain wrench, Fig. 6 (Cancelled), hammers 52-54 act directly on the pipe 51 and are connected by supply pipes 55-58 passing through the pivots of the chain ; the hammers may be inclined to the radius of the pipe to give a turning effect. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to Internal Combustion Engines.
IPC: F01B7/20
Filed: 1917-05-17
Abstract: 116,736. Marks, E. C. R., (Tygard Engine, Inc.). May 17, 1917. Valves; valve-gear.-A two-stroke-cycle engine using mixtures of air with coal-dust, gas, liquid hydrocarbon or alcohol has one or more pairs of working and pump cylinders S', S arranged coaxially with a partition between them containing a rotary conical distributing valve. Charges of combustible mixture are drawn into the pump S through ports R in a rotary valve D, Fig. 4, when a port R<6> therein registers with a supply orifice R<2>. Each pair of ports R<6>, R opens into one of four chambers in the valve formed by longitudinal partitions Q having passages T for the circulation of cooling water which enters and discharges through ports U. The charges compressed in the pumps are stored in the valve chambers and subsequently admitted to the expansion cylinders at the ends of exhaust strokes, the combustion gases escaping through a port R<6> when it registers with a port R<3>. The valve is driven through chain gearing at one-fourth the speed of the crank shaft, and is secured to the gear wheel P<1> by a pin X of soft metal adapted to shear in the event of the valve seizing. In an engine using liquid fuel, air may be compressed in the pump spaces, the fuel being injected into the combustion cylinders through ports 17 in the valves; ignition is effected by the heat of compression. Other means for effecting ignition comprise a continuously burning flame R<4> fed from a by-pass R<5> communicating with the valve chambers, or an incandescent body 19 on the face of the piston. When using solid fuel, coal or other combustible is fed through a hopper containing a rotating member with a serrated surface for reducing the fuel to suitable dimensions. Air is drawn through the hopper and mixes with fuel to form a combustible mixture.

Patent GB-690149-A (GB)
Title: Improvements in the production of organic oxygen-containing compounds
IPC: C07C27/22
Filed: 1951-03-29
Abstract: <PICT:0690149/IV (b)/1> In a process for the production of organic oxygen - containing compounds by adding on carbon monoxide and hydrogen to olefinic compounds while employing as catalysts vaporous cobalt compounds, in particular cobalt carbonyls, which are introduced into the reaction chamber in vapour phase, the vaporous cobalt compounds are produced by the continuous introduction of cobalt or cobalt compounds in finely-divided solid form into an otherwise empty vessel in countercurrent to flowing carbon monoxide or mixture of carbon monoxide and hydrogen intended for the reaction under increased pressure and at elevated temperature such as are necessary for the formation of the vaporous cobalt compounds.  The cobalt or cobalt compounds may be charged to only part of the carbon monoxide or mixture of gases followed by dilution with more synthesis gas.  In the drawing cobalt metal or oxide is withdrawn from a pressure-tight reservoir A by means of conveyor worm B operating at constant speed and introduced into the upper end of a high-pressure pipe C heated by heating devices D1 and D2 through which the synthesis gas is led.  The cobalt material entering the gas current is converted to volatile cobalt compounds, mainly carbonyl and hydrocarbonyl, which are entrained by the current of synthesis gas and led through the heated pipe connection E into reaction vessel F where the synthesis gas and olefine introduced through the pipe G react to form aldehydes.  Any other charging device may be used instead of the conveyer worm, e.g. a constant amount of cobalt material may be allowed to trickle into pipe C by means of a slide or regulatable valve.  A second chamber may be arranged above reservoir A which can be independently released from or placed under pressure and from which cobalt material introduced may be emptied through a valve into reservoir A.  When the cobalt material in A is almost used up the upper container is opened, freshly filled, placed under pressure and the introduced amount emptied into A.  The two reservoirs may alternatively be in parallel.  In an example, isobutylene is reacted under pressure with carbon monoxide and hydrogen in the apparatus using cobalt oxide as the source of volatile carbonyl compounds to produce isovaleraldehyde. Specification 644,665 is referred to.
Patent GB-145142-A (GB)
Title: Improvements in electric relays, applicable more especially to relays for use in railway signalling apparatus
IPC: B61L23/12
Filed: 1919-03-24
Abstract: 145,142. Sykes Interlocking- Signal Co., W. R., and Tarrant, R. W. March 24, 1919. Electrical systems, non-automatic; signalling- instruments; signalling-instruments, interlocking -A relay comprises a polarized and an unpolarized electro-magnet arranged to interact so that when the relay is applied to an interlocking railway signal system, the " line clear " operation when once performed cannot be repeated until a " train on " signal has been sent. According to the Provisional Specineation, the relay can be used to control a three-position indicator. The lower winding b has a permanent magnet g and an armature b<1> which rests normally against the adjustable pole f<1>. When the winding receives a current of the correct sign, the armature is moved over to the other adjustable pole e<1>, where it remains until returned by an impulse of reverse sign. When moving to the left, it draws with it the armature a<1> which adheres magnetically to the soft-iron roller d and closes a holding circuit at k to energize the coil a, which produces a weaker field than the coil b. The armature a<1> then adheres to the soft-iron mass j, but is returned by gravity or a spring when the circuit of the coil a is broken externally, or when the armature b<1> strikes it back on receipt of a current of reversed sign. An outgoing signal is given from the block instrument T' by pressing the plunger Q, the polarity of the current sent to the line 11 being determined by the setting of the commutator R. An incoming " line clear " current over the line 11 affects the instrument T<2> and also the polarized electro-magnet b. The armatures b<1>, a<1>, thereupon move to the left as described above, and the in-coming current is admitted through contact k to the self-holding winding a and also, as soon as the trigger switch V has been operated, to the coil W which unlocks the starting-signal lever. The moving of this lever breaks the above-mentioned circuits at U, and the armature a<1> thereupon breakus contact at k. Unless, however, a reverse current signifying " train on " be then sent to return the armature b<1>, further " line clear " signals will not affect the armature a<1>, and the starting-signal lever will not again be unlocked.

Title: Improvements in thermostatically controlled enclosures
IPC: G05D23/275
Filed: 1950-03-23
Abstract: 695,631. Automatic temperature control systems. DAVIS, N. R., and SUNVIC CONTROLS, Ltd. March 21, 1951 [March 23, 1950], No. 7335/50. Class 38 (iv). [Also in Groups XIII and XXXVII] An electrically heated enclosure for the cold junction of a thermocouple (or standard cell, or quartz crystal) is temperature controlled by a switch comprising two bimetallic elements, one responsive to the temperature of the enclosure, the other responsive both to the outside temperature and to a " cycling " heater. A metal block 1, Fig. 1, has a bore 2 to accommodate the cold junction (not shown) of the thermocouple; a second bore 4 to accommodate the main bimetallic helix 5; and is surrounded by an electric heating element 3, and by a plastic outer casing 25. The helix 5 operates a rod 6 to actuate a spring-mounted contact 10, Fig. 2, co-operating with a contact 11 mounted on a bimetallic strip 12 carrying an auxiliary heater 19. A permanent magnet 18 provides a snap-action for the switch. The strip 12 is insulated from the heat of the block 1 by an insulating disc 20 and is in thermal contact with the metal end cap 28 of the assembly so that it will tend to open the contacts in response to a rise in the outside temperature, as well as when heated by the auxiliary " cycling " heater 19 which is connected in series with the heater 3 whenever the contacts are closed to energize heater 3.

Title: Improvements in or relating to quick cooking rice products and process of preparing same
IPC: A23L7/196
Filed: 1943-05-10
Abstract: 579,981. Rice. STEVENS, A. H. (General Foods Corporation). May 10, 1943, No. 7374. [Class 58] A quick-cooking rice product is prepared by cooking rice for a period sufficient to gelatinize the starch and increase the moisture content to about 65-70 per cent. without causing substantial damage thereto and then drying the swollen grains by removing moisture from their surfaces at a rate sufficiently faster than it can diffuse thereto from their interiors so as to set them in their enlarged condition and produce a porous structure therein. The rice may be soaked initially for 30-60 mins. in cold or warm water below the gelatinization point, i.e., 65-70‹C., and may be cooled before drying by means of cold air or water. Soaked rice is cooked in boiling water for about 8-10 mins. and unsoaked rice for about 21-23 mins. After cooking and draining, the rice may be spread in a layer not more than about 1 in. in depth and dried by forced air circulation. With an inlet temperature of 140‹C. and an air velocity through the grains of 200 ft. per min., the grains are dried to 8-14 per cent. moisture content in 10-15 mins. Vitamins and other nutrition principles may be added as by immersing the grains in, or spraying them with, a solution thereof before or after drying. The product may be prepared for use by cooking in 1-1¢ times the volume of boiling water for about 2-3 mins. or by soaking in warm or cold water or milk.

Filed: 1973-02-15
Abstract: 1346044 Inserting terminals in panels; Shearing AMP Inc 15 Feb 1973 [29 Feb 1972] 7405/73 Addition to 1345861 Headings B3A and B3W Apparatus for severing terminals 2 from a carrier strip 1 and securing the terminals to a panel 63 comprises, a mechanism 54 for intermittently feeding the strip along a feed path to position terminals at a shear block 36, Fig. 5, a U-shaped member or terminal holder 40 comprising an arm 48 serving as a terminal gripping member and an arm 41 joined thereto by a portion 45, the shear block being slidably positioned between the arms against the portion 45, the arm 48 being relatively biased towards the shear block by a spring 44 for gripping a leading terminal of the strip, the shear block 36 co-operating with a shear blade 51 to sever the leading terminal and to position it in the, path of an insertion punch 15. The panel 63, Fig. 2, is placed on an anvil 66 and a ram 9 is driven downwardly. As the ram moves, cam surfaces 23, 24 engage a roller 30 to pivot a lever 25 counter-clockwise, Fig. 4 (not shown). The shear block 36 is thereby moved to the right, Fig. 3, shearing the leading terminal 2 from the strip 1 against the shear blade 51, Fig. 6 (not shown). The sheared terminal is held between edges 52, 53 of the shear blade and shear block by the spring 44 and is positioned over a hole 69 in the panel 63. The punch 15 descends with the ram and grips the terminal as the lever 25 begins to pivot clockwise, thereby holding the terminal and the terminal holder while the shear block 36 is withdrawn clear of the path of the punch. As it travels downwards the punch engages the arm 48 and pushes it out of its path against the bias of the spring 44. When the ram 9 is at the limit of its travel a post portion (4), Fig. 1, (not shown) of the sheared terminal has been inserted in the hole 69 and a plunger 67 in the anvil is depressed against a spring bias. The ram is then retracted returning the parts to their original positions. The feed mechanism 54 is driven by a cam on the ram 9 and indexes the strip 1 in synchronism with movement of the shear block.

Abstract: 1373685 Cutting concrete blocks HEBEL GASBETONWERK GmbH 18 Feb 1972 [20 Feb 1971] 7700/72 Heading B5A [Also in Division B8] A cast concrete block is stripped from the mould, and divided by cutting wires in a first direction and then in a second direction transverse to the first, the cut block then being rotated through 90 degrees and placed in an autoclave for steam hardening. As described for a rectangular reinforced block 1 (Fig. 2a), cast flat or on edge, and to be cut into plates or bricks, the stationary block is first cut longitudinally by stretched wires 3 on a movable carriage 2, or by fixed wires 14 (Fig. 7a), while the block moves in direction A. Transverse cutting is effected while the block is on edge by wires 8 (Fig. 4a), that reciprocate vertically and horizontally. Cutting machine.-A cast, rectangular block is lifted to a cutting station 15 (Fig. 10), by tongs or suction and on to a table 16 grooved to receive guide rods 29 attached at one end to a frame 30, and at the other end to a portal 32 via cutting wires 31 (Fig. 11). The portal 32 and frame 30 travel on rails 33 to cut the stationary block lengthwise (alternatively, the block moves in a direction V (Fig. 10), while the wires 31 are stationary). After cutting, the table 16 moves on rails 19 to a station 20, where a vertical plate 24 (Fig. 13), is mechanically interlocked with table 16, and the table and plate rotated hydraulically to stand the block on edge on the plate 24. Table 16 is returned to a horizontal position and to the cutting station 15 (Fig. 10), while the block and plate 24 (Fig. 13) are moved by a carriage 23 to a station 21 for cutting transversely by wires stretched in a frame 41. The carriage 23 returns the cut block to the station 20 (Fig. 10), where the vertically arranged grid 27, moved from an unloading station 25, and the plate 24 (Fig. 13), rotate the block back through 90 degrees to a horizontal position (see Fig. 14, not reproduced). The grid 27 (Fig. 10), and block are removed to an autoclave. In an alternative embodiment (Figs. 15- 17, not shown), the block is moved between stations 15, 20, 25 (Fig. 10), by a grid movable on rollers and raised through the cutting table 16 to lift the block away.
